What development if any could turn this around?
- Affordability of quality rifles,
- Availability and affordability of off-the-shelf ammunition.
Recoil has always been and will always be a factor. As smaller caliber cartridges start to increase in bullet weight, to keep up with the velocities, more powder needs to be used and hence more recoil.
I don't see the 338's going away. 338 WinMag, 338 RUM, 33 Nosler, 338 Lapua and 338 Norma Mag --they're all fine cartridges and they satisfy different needs.
There was a 2K challenge about five or more years back where
@Alex Wheeler placed 3rd or 4th, and IIRC he was shooting a 338. The results were posted here on LRH.
@fruitnut, you keep mentioning the 338 Edge. Carlock's design is an excellent cartridge, and he's improved on it since. However, you cannot find readily available ammunition for it, which I would wager eliminates >90% of shooters as people who would use and promote the cartridge.
The small stuff offers very little room for error.
This is exceptionally true. What comes across to me as you quote statistics and BC is that it doesn't seem that you have spent a lot of time shooting the different cartridges. Once you have spent a lot of time (and money) shooting lead at tiny white dots on far away hillsides, you really come to appreciate what the 338 can do well. Sure, my 338 Edge is a tad heavier than
@RH300UM's, it is what I bring if I anticipate that I'm shooting past 500. I'm not thrilled that I use a brake for it, but it keeps the recoil down to between a 308 and '06.
It has been mentioned, the burden of a rifle weighing >11 lbs. Have you seen what the Cheytac or Barrett rifles weigh?
What it really comes down to is know your skill and know the limitations of your cartridge.
